  "verdict": "Implemented the frozen-threshold Adam controller as a local optimizer-training intervention on the structurally matched dynamics track. Across 8 paired seeds, the tuned controller achieved lower test MSE than the tuned Adam baseline (delta_mean=-0.00023498, permutation p=0.0081), satisfying the bench criterion for a significant win. The trained-model mechanism diagnostic was computed from HVP sharpness, Adam second moments, and actual controlled rates; observed maximum w=0.6364 stayed below the predicted boundary 2.0 and target 1.8, so the controller was mostly inactive in this regime.",
